Note 23 — Chapter I · THE CHÁRVÁKA SYSTEM.

This refers to an obscure śloka of Udayanáchárya, "where a reciprocal and a non-reciprocal universal connection (i.e., universal propositions which severally do and do not distribute their predicates) relate to the same argument (as e.g., to prove the existence of smoke), there that non-reciprocating term of the second will be a fallacious middle, which is not invariably accompanied by the other reciprocal of the first." Thus "the mountain has smoke because it has fire" (here fire and smoke are non-reciprocating, as fire is not found invariably accompanied by smoke though smoke is by fire), or "because it has fire from wet fuel" (smoke and fire from wet fuel being reciprocal and always accompanying each other); the non-reciprocating term of the former (fire) will give a fallacious inference, because it is also, of course, not invariably accompanied by the special kind of fire, that produced from wet fuel. But this will not be the case where the non-reciprocating term is thus invariably accompanied by the other reciprocal, as "the mountain has fire because it has smoke;" here, though fire and smoke do not reciprocate, yet smoke will be a true middle, because it is invariably accompanied by heat, which is the reciprocal of fire. I wish to add here, once for all, that I own my explanation of this, as well as many another, difficulty in the Sarva-darśana-śaṅgraha to my old friend and teacher, Paṇḍit Maheśa Chandra Nyáyaratna, of the Calcutta Sanskrit College.
